Dr Lee game

Help Dr Lee in this crazy adventure game. Start flying to earn cash and upgrade the rocket. Earn coins by collecting $ floating around in the sky. Blast your way into the clouds going upwards, but the main aim is to get as far as you can for a higher position on the scoreboard. The more upgrades you get the easier flying will become, you can purchase these upgrades with FOG coins and bank any extra cash you earn in game.
